Diffusion Zinc Plating of Structural Steels

摘要

The report deals with the research on diffusion zinc plating of structural steels when replacingrntheir cyanide cadmium plating. The results of the experiments in the open air, in vacuum, inrnthe inert atmosphere, under various temperatures (300 – 500℃) for different steel brands arernpresented. It is shown that diffusion zinc plating in argon or nitrogen atmosphere ensuresrnobtaining the qualitative anticorrosion coating with insignificant change of mechanicalrnproperties of steels. The process is simple, reliable, ecology pure and cost-effective.
